Claims4
An actuator for a push button switch comprising a housing, a plunger means, and a spring,
- the housing comprises a base, the base having an upper surface from which outer walls extend defining a first cavity, inner walls extend from said upper surface defining a second cavity, and an aperture provided therethrough within said second cavity, the outer walls surrounding the inner walls in varying spaced relation, the base having means for engaging a push button switch,
- the plunger means comprises a base portion, the base portion including an upper surface, a cap engaging portion extending from the upper surface, and an edge defining a central, through aperture, and a tubular prolongation extending away from the base portion, the tubular prolongation including an outer surface and a terminal end with a through hole formed therein, and
- the spring comprises a spring body and a lead extending therefrom such that the spring and the plunger means define a sub assembly with the spring body circumscribing and abutting the outer surface of the prolongation and the lead extending beyond the prolongation, the sub assembly positioned within the second cavity of the housing with the lead of the spring extending through the aperture within said second cavity of the base of the housing.
